So, it is more necessary to predict the average surface roughness of the materials.
Composite is a materials system composed of two or more physically distinct phases whose combination produces aggregate properties that are different from those of its constituents.
Three types of materials were used to prepare the specimen, with 3%, 6% and 9% by weight of SiCp reinforcement with average particle size of 40µm.

These problems will affect the engineering structures which related to the stability and safety of the materials.
This observation indicate that the strength of the materials increases subjected to normal stress and decreases subject to shear stress.
This observation indicate that the strength of the materials decreases as increases for shear and mixed stresses.
However the strength of the materials increases as increases for all various stresses.
